Summary

0000237: Vehicle PhysX / Teleportation issues. [M1 Abrams & Bradley]

Description

Some vehicles (Bradley 'RHS_M2A3_BUSKIII' & M1 tank 'rhsusf_m1a1aim_tuski_d' ) have a random tendency when driving that they appear to be 'teleporting' into a void grey area to the user. Video (From bradley commander view) - https://www.youtube.com/watch?v=3aFxiISqCCU&feature=youtu.be [^]

My guess is that this is a PhysX issue note in the video the speed goes to >70,000 km/h and the rpt on the server is spammed with the following when this occurs:
'2015/02/01, 0:12:00 Matrix is not valid as physx transform!'

The server fps went down to 0 FPS causing desync. I was able to bring up the debug console up retrieve the position of the effected vehicles, it returned something like [#QNAN,#QNAN,#QNAN]. I was able to call setPos on the vehicles to teleport them to [0,0,0], after doing this the server FPS and desync promptly went back to normal.

My best guess is that something is wrong with the PhysX configurations but I am no expert in the Arma 3 engine. Unfortunately this makes these assets fairly unusable if there is a high probability of this occuring and in both missions we ran with 3-7 of these assets it happened in both, with 1 bradley suffering this in the first mission, and later 1 M1 and one bradley.

Steps To Reproduce

Unfortunately this is difficult to reproduce but we have had this happen three times last night, with approximately 10 of these assets crewed by players. Maybe the video will be of some use. It happened to me later and I could upload a video of that if it is useful.
